AM493 Series Tek-Guardâ„¢ Vandal-Resistant Apt. Intercom Entrance Panel

The Alpha Communications® / TekTone AM493 series Tek-Guard™ Vandal-Resistant entrance panel is a modular series, typically used with our TA205B or TA205C series duplex type, handset suite stations and PK205 system amplifier.

Panels are equipped with a mylar, voice-frequency response speaker and dynamic microphone protected by louvered speaker grilles. The speaker panel can accommodate up to 16 push buttons. The aluminum push button actuators may be engraved with up to four letter/digit combinations (at extra cost). For more than 16 suites the AM493 is used in conjunction with the AM490 series push button panel modules (without a speaker/microphone).

Pressing the button corresponding to the desired name and suite number causes a signal at the apartment station. The resident may then converse with the caller. Controlled entry is permitted by push button operation of the electric door release. AM493 panels with 0 - 8 buttons are available with postal option (add suffix 'P' to the model number).
